Compared with the prior art, the golden hydrotherapy composition has remarkable effects of fading and removing spots and is also capable of obviously increasing water content of skin and brightening whole skin color of a face.

The invention relates to a method for preparing a transparent skeleton specimen of a small animal, and a specimen prepared with the method. According to the invention, muscle of the small animal become transparent, and a colouring agent is adopted for soaking to develop and distinguish different parts of an animal body, so that original position structures of hard bones and cartilages of the animal body are showed directly and accurately. The method is simple in step, the adopted agent is safe and can be used for preparing transparent skeleton specimens of small animals such as goldfishes, tropical fishes, frogs and mice, the prepared specimens can be kept for a long time, structures are showed clearly, and the prepared specimens have relatively high scientific research and teaching values.

The invention relates to a fish molecular design breeding technology, in particular to a goldfish gene editing technology and a method for creating a new goldfish variety by using the gene editing technology. The method comprises steps of knockout target design, microinjection, fertilization incubation, gynogenesis and high-temperature sex reversal. According to the invention, a CRISPR / Cas9 gene editing technology is established on goldfish, so that a target phenotype is generated on F0 generation goldfish, an efficient gynogenesis condition of pleated Thai lion goldfish is determined through experiments, homozygotes are obtained in F1 generation, and a large number of groups are expanded in F2 generation through temperature-induced reversion. Through a molecular breeding means, transfer of a single target character is rapidly achieved, the goldfish gene editing technology and the method can be used for creating a new goldfish variety, provides technical support for molecular design and breeding of goldfish, and is beneficial to promote development of goldfish molecular breeding technology.

The invention discloses a newly bought goldfish feeding water-passing intelligent motor device. The newly bought goldfish feeding water-passing intelligent motor device comprises a machine body, wherein a main space is formed in the machine body, a small space is formed on the lower side of the main space, a pause space is arranged on the lower side of the small space, and a pause device is arranged in the pause space. Newly bought goldfishes can automatically pass water, so that the goldfishes are prevented from directly entering a new environment of a fish tank and getting sick or dying due to the fact that the goldfishes do not adapt to the suddenly and violently changed environment. Two processes of temperature balance and water environment change balance can be controlled through a motor controlled through temperature. A motor controlled through continuous pressure is used for monitoring the possible inadaptation phenomenon of the goldfishes in the water passing process in real time, water passing is temporarily stopped to be buffered by the goldfishes, and it is guaranteed that water passing is normally completed.
